Product Introduction
The conical auger of a rotary drilling rig is a drilling tool suitable for loose formations, gravel layers, and complex geological conditions. The main feature is that the diameter of the spiral blades gradually increases from top to bottom, forming a conical structure that can adapt to geological changes during drilling, and improve slag discharge efficiency and anti sticking drilling ability.
Working principle:
When drilling, the bottom flight first drill in the formation, expands the diameter of the borehole, and creates slag discharge space for the upper flight.

Working principle:

Progressive contact: The conical structure gradually increases the contact area between the drill bit and the formation, avoiding instantaneous jamming.
Reverse escape: When encountering a stuck drill, the drilling rig can reverse the drill rod and use the reverse spiral force of the conical blades to exit the stone.
